Abstract
Description
Technical Field
[0001] This utility model relates to the field of calibration device technology, specifically to a calibration device for an ozone concentration analyzer. Background Technology
[0002] The calibration device mainly includes an ozone generator, a standard concentration reading device, a zero-point gas generator, auxiliary equipment, and a calibration system. By generating ozone gas or ozone water of known concentration, combined with high-precision detection instruments and equipment, it can accurately calibrate the ozone concentration analyzer.
[0003] Ozone concentration analyzers typically operate based on principles such as ultraviolet absorption, chemiluminescence, or electrochemical methods. They indirectly measure ozone concentration by detecting the ozone's response to specific physical or chemical processes. Regularly calibrating the analyzer with a calibration device is crucial for ensuring its long-term stable operation and measurement accuracy.
[0004] However, since the calibration device needs to use a precision flow meter and solenoid valve to ensure the accuracy and stability of flow control, and as the gas pressure increases, the sealing pressure at the connector will also increase accordingly. Long-term exposure to high pressure will cause fatigue of the connector material, resulting in reduced tightness of the connector and increased risk of leakage. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a technical solution: a calibration device for an ozone concentration analyzer. Please refer to [link / reference]. Figure 1 It includes a calibration device housing 1, and a control panel 2 is mounted on the surface of the calibration device housing 1. Please refer to [link / reference]. Figure 2 The calibration system controller 3 is installed inside the housing 1 of the calibration device. A displacement sensor 4 is installed on the surface of the calibration system controller 3. A pressure sensor 5 is installed on the surface of the displacement sensor 4. A temperature sensor 6 is installed on the surface of the pressure sensor 5.
[0028] The calibration system controller 3 is responsible for controlling parameters such as gas flow rate, concentration, and time during the calibration process. It can automatically adjust the output of the ozone generator through a preset program to achieve ozone calibration at different concentrations.
[0029] Displacement sensor 4 is used for mechanical structure adjustment or positioning, pressure sensor 5 can monitor pressure changes inside the analyzer, and temperature sensor 6 can monitor the working environment temperature.
[0030] Please see Figure 1 The transmission pipes 7 are located on both sides of the surface of the calibration device housing 1. Please refer to [link / reference]. Figure 3Auxiliary fixing pipes 8 are installed on the surface of the transmission pipe 7, and baffles 9 are installed on the surface of the auxiliary fixing pipes 8.
[0031] Connector 10 is located at the interface of transmission pipe 7. Please refer to [link / reference]. Figure 5 Both the connector 10 and the auxiliary fixing tube 8 have threaded grooves 11 on their surfaces. Both the connector 10 have sealing sleeves 12 screwed onto their surfaces. The right side of the sealing sleeve 12 has a positioning block 13. A flange 14 is installed on the outside of the connector 10's interface. Threaded rods 15 are evenly distributed on the surface of the flange 14.
[0032] Connecting the connector 10 to the auxiliary fixing pipe 8, and making the rotating sealing sleeve 12 in close contact with the surface of the baffle 9, can seal the connection between the connector 10 and the auxiliary fixing pipe 8. The rotating positioning block 13 can squeeze the sealing sleeve 12 to prevent it from loosening. By rotating the threaded rod 15, the flange 14 can be fixed at the interface of the ozone concentration analyzer, thus ensuring a stable connection between the connector 10 and the ozone concentration analyzer interface. This prevents the connector 10 from becoming less tight after long-term use, reducing the risk of leakage.
[0033] Each connector 10 has a first insertion tube 16 installed on its left end. The first insertion tube 16 is inserted into the inside of the transmission pipe 7. A first sealing ring 17 is installed between the connector 10 and the auxiliary fixing pipe 8, which improves the stability of the connection between the connector 10 and the transmission pipe 7.
[0034] A second insertion tube 18 is installed on the right end of the connector 10. A second sealing ring 19 is fitted onto the surface of the second insertion tube 18. The second insertion tube 18 is connected to the interface of the ozone concentration analyzer and is sealed by the second sealing ring 19.
[0035] Please see Figure 6 Bolts 20 are evenly screwed onto the inner ring of flange 14, and the connecting ends of bolts 20 are all screwed onto the surface of connector 10, which improves the firmness of flange 14.
[0036] Please see Figure 2 An air inlet 21 is provided on the left side of the calibration device housing 1, and an air outlet 22 is provided on the right side of the calibration device housing 1, so that the gas inside the calibration device housing 1 can circulate with the outside.
[0037] In operation, the following steps are taken: First, the first insertion pipe 16 is inserted into the transmission pipe 7. A first sealing ring 17 is installed between the connector 10 and the auxiliary fixing pipe 8, improving the stability of the connection between the connector 10 and the transmission pipe 7. The second insertion pipe 18 is connected to the interface of the ozone concentration analyzer and sealed by the second sealing ring 19. Then, the connector 10 is connected to the auxiliary fixing pipe 8, and the rotating sealing sleeve 12 makes tight contact with the surface of the baffle 9, sealing the connection between the connector 10 and the auxiliary fixing pipe 8. The rotating positioning block 13 can maintain the sealing sleeve 12. The compression prevents the sealing sleeve 12 from loosening. By rotating the threaded rod 15, the flange 14 can be fixed at the interface of the ozone concentration analyzer, thus ensuring a stable connection between the connector 10 and the ozone concentration analyzer interface. This prevents the connector 10 from becoming less secure even after long-term use, reducing the risk of leakage. Finally, the calibration system controller 3 controls parameters such as gas flow, concentration, and time during the calibration process. It can automatically adjust the output of the ozone generator through a preset program to achieve ozone calibration at different concentrations.
